2 Claims.

My invention relates to a one piece type of box with cover attached,which can be shipped flat or in knocked-down form, and can be erectedreadily for packing by the user. It is an object 5 of my invention toproduce a box of the character noted, which will provide both a bottomand lid havingfront and side walls, said walls being joined at cornerswhere they meet, the back wall having at its lateral edges intermediatecorner- 10, connecting sections between the side walls -of both thebottom and the lid, which intermediate corner-connecting sections arecaused to adhere to the said back wall and are provided with diagonalfold portions which are left free and are ll. connected respectively tothe side walls of both the lid and the bottom so as to permit readyerection of the said side walls. It is one of my objects to so arrangethe dimensions and outline of the blank structure that in the cuttingthereof there is a considerable saving on paper board when I employ ashallower lid than bottom. A structure such as has'now been brieflydescribed can be very easily erected since the act of raising the sidewalls of the knocked-down structure will '1 result in raising the backwalls; My invention is further well adapted for tlie-style of box inwhich panels on the front walls can be secured to reversely foldeddiagonal portions of the side walls at the corners of they structure,thus providing for stiffness of the side walls when the same is erected,either with .the intermediate cornerconnecting sections adhered to theback wall,

or not.

I have illustrated as; invention is embodied in the accompanyingdrawings, but without intent thereby to limit the application of theinvention to such forms alone, and I refer to the appended claims asstating the invention inherent in my disclosure.

Figure 13 is a perspective showing the erection of this second form ofbox.

Figure 14 shows a blank such as is illustrated in Figure 2, but in whichthe lid and bottom portion have sides of equal depth.

Figure 15 is a plan view showing the mode of cutting the box blanks froma piece of paper board without waste so as to effect a saving ofpractically all of the board not used because of the lid being shallowerthan the main box portion or bottom.

The structure of the first or preferred form of my invention can bemanufactured by the mechanism and methods described in my Patents No.1,926,364, issued September 12, 1933, and No. 1,974,408, issuedSeptemberlfi, 1934, and as disclosed in my co-pending application SerialNo. 129,900, filed a pair of timed glue wheelsto the mechanism thatcarries the blank in the initial direction of motion, as will be morefully noted below.

Referring now to the drawings and the first or preferred formillustrated therein, I show a box blank having a main bottom panel I,having side panels 2, 2, a wall 3 which for convenience will be called afront wall, and a wall 4 which for convenience will be called a backwall. Articulated to this back wall is the main body panel 5 of the lid,'said lid having side walls 6, 6, and a lid front wall I.

Extending laterally from the front wall panel of the box bottom portionare the corner sustaining flaps 8, 0, and like corner sustaining flaps9, 9, extend laterally from the lid front wall panel. The side'panels 2,2, have diagonally scored portions 2a, and the side panels 6, 6, havelike portions 5a, 6a. v

Between the side wall panels of the lid and bottom portions of the blankare intermediate, corner connecting sections having diagonal lines offold therein. They may be described as having a median portion Ill, withtriangular sections II, II and l2, l2 articulated by diagonal fold linesto the median portion and to the respective side walls by a fold linenormal to their length.

In this particular form of blank the sections H, II are shaped to permitof cutting the blanks from a. sheet without waste of the board which isnot used due to theshallowness of the lid sections. My arrangementavoids staggering of the blanks when cutting them from a sheet, thussaving end wastage and avoids loss of any board due to the narrowerlidsand wider bottoms being cut from the sheets as one piece. Thus thesections H, H extend from the outer end of the diagonal 55 March 9,1937, by the addition of fold line adjacent to the main portion orbottom portion of the box, on a slanting line Ila, and thence on a linellb which is an extension of the boundary of the side wall panels 2.

Thus, as shown in Figure 15, the blanks can be cut from a sheet with thetrapezoids H, II staggered, but the remainder of the blanks merelyshifted end for end, with no waste whatever, and with a saving of all ofthe board not used in making the shallow lid sections. A furtheradvantage is that the intermediate corner connecting sections are cut ona bias in a manner to provide a maximum area of material for eachadjoining blank.

Referring now to the formation of the box adapted for automatic machineoperation, as well as hand operation, the first stage as shown in Figure3 ,is to fold the diagonally scored sections 2a, 2a and 6a, Go backagainst the under side of the blank. During the same stage adhesive willbe applied as at Illa, Illa. t'o the back wall 4, or to the portions ll]of the corner sections or brfih.

Then in the next stage, as shown in Figure 4, the

side panels along the entire structure are folded inwardly thus causingthe portions ii Hi to adhere to the back wall, and bringing theunderturned sections 2a, and 6a, uppermost.

-In automatic machinery it will then be best to change the direction ofmovement of the blank as indicated in Figure 5, whereupon adhesive willbe applied to the inturned flaps 8, 8 and'9, 9 which flaps I have termedthe corner sustaining flaps, as indicated in Figure 5. The finaloperation will be to turn the respective front panels, now lying at thesides of the blank, inwardly over the remainder thereof, which resultsin causing the adherence of the sustaining flaps to the triangularportions 2a, and 6a.

The knocked-down structure is now complete and can be stacked in anordinary set of stacking belts, while the adhesive becomes set, andpermitting the removal of a stack of blanks at a time for placing inshipping packages The erection of the box is illustrated in Figure 45 7.The first operation is to lift the sides of the main or bottom portionand of the lid. This will swing the sustaining flaps into positionagainst the bottom of the main portion and will hold the side walls intheir erected position. The act of lifting the sides also serves toswing inwardly the sections H and I2, since the sections l0 of thecorner portions are held against the back wall 4, an operation whichswings up the back wall. The box is then ready for filling after whichthe lid is ready for closure by raising the lid side walls and placingthe opened lid over the bottom.

It will be noted that the box as described above can also be utilizedwithout the adherence of the intermediate connecting corner sections tothe back wall.

The closed box is illustrated in Figure 1, and will be very strongagainst collapse, having four corner sustaining flaps and having bothside and end walls of the lid engaging over the side walls and frontwall of the box, and having a back wall reenforced by the adheringportions ID of the connecting portions between the lid and the rest ofthe box.

In Figure 14 is shown a box in which the lid has the same depth as thebox. In this form I have numbered the parts in the same manner as in thefirst form shown. It will be noted that the sections l0, I come to apoint, instead of having any lengthwise dimension intermediate the endsof the diagonal fold lines.

In Figures 9 to 12, inclusive, is shown a structure in which there areno corner sustaining. flaps and the diagonal scores permitting collapseof the box and the forming of the same in knock-down condition arelocated in the ends of the blank.

In this form I have illustrated the panels of the lid and of the mainbox portion or bottom, at 20 and 2|, respectively, the side walls of thelid and bottom at 22 and 23, respectively, the flaps at the front walls24 and 25 of the lid and bottom being indicated at 26 and 21, and thediagonal scores at 23 and 29 in the said two front walls.

In this form I have illustrated the intermediate corner connectingsections at each side of the blank with the same numerals as in thefirst form because they are the same. Thus in' this blank there are thesaid comer sections having the portion I, II and I2 at each side of themain back walls 4.

In forming this box, the first operation is to fold the front walls ofthe bottom and lid on the diagonal'scores to the position indicated at28a and 29a for the two portions respectively in Figure 10. Then theadhesive is applied on the turned-in flaps 26 and 21, and also at theback wall 4, at the areas Illa as in the first instance. The finaloperation is to turn the sides of the complete blank inwardly causingthe several portions with adhesive between them to adhere together. Thecompleted box is delivered in knock-down form for shipment, and as showncorner sustaining flaps which require some manipulation of the box inorder to keep the front walls of the bottom and the lid erect andprevent the box from collapsing during filling. When closed the box ofthis form will be quite rigid and self-sustaining against collapse.

Referring for a moment to Figure 8, I have shown the mechanism indiagram which can be used for forming the box of my first form.

The blanks from a stack 30 are delivered to a conveyor having studs 3|thereon, which causes them to pass between flap deflecting wheels 32, 32which turn down the corners diagonally connected with the side wallportionsat the forward and rearward ends of the blank. Sweeps 33assisted by positive deflectors 34, complete the turning under of thesaid diagonal portions. I have indicated an adhesive-applying device 35for applying the adhesive at the spots Illa.

After passing the adhesive-applying devices, the next operation is toturn in the entire sides throughout the blank on both lateral edgesthereof, resulting in the adherence of the portions In to the back wallof the structure, and in the second illustrated form completing the box,additional gluing and folding devices being required for the first formaccompanied by change in orientation of the blank to the line of feedingportion.

It can be noted from the above that the addition of a single applicationof adhesive, is the only diii'erence in the operations of forming thebox with attached lid, over the operations of forming a box without alid but having the front and rear ends corresponding to each other. Inmy new form the front wall of the lid is formed by the mechanism or inthe manner in which the rear wall of a box without a lid is formed, andall that is required is to retime the folding devices and respace them,which is incident to machines used industrially for making difierentsized boxes without the lids.

Having thus described my invention, what I claimas new and desire tosecure by Letters Patent isav 1. A one-piece box 'withlid in knock-downform, comprising a bottom and a lid, the lid being hinged ,to the backwall of the bottom, and intermediate sections connecting the back walland the side walls of the bottom and lid, and the side walls and' frontwalls of the lid being of substantially less depth than those of thebottom, and -the intermediate sections being so shaped as" to permit ofstaggering said sections in blanks for said boxes turned end for end and2. A blank suitable for forming into a'one piece knocked -down box withlid attached, comprising a main bottom panel with a front wall, two sidewalls and a back wall attached thereto, and attached to said back wall amain lid panel having a front wall and two side-walls, there beingintermediate sections with diagonal lines of fold therein connectingsaid back wall and said'lid and bottom side walls, the walls of thebottom being of greater height than the walls of the lid,

and the said intermediate sections being cut on a bias, the ends ofwhich bias-cut are defined substantially 'by the respective heights ofsaid bottomand lid side walls.
